Paper for me at this moment!
SCRAP PAPER
Holds my ideas and the way I develop them as notepaper, drafts and mockups.
Print and make papercraft.
Recycle at the same time.
COPYPAPER
Even some of the cheap stuff is acid free so good for archival purposes.
OLD BOOK PAGES
Thick newsprint good for printing/painting/drawing on.
AVAILABILITY
If you're resourceful you'll find it everywhere.
Wrapping / florist papers
PLUS all the lovely stuff you can buy
Love it! :) [heart,heart,heart]
